Express the following in the SIGMA notation: a. x1 +x2 +x3 +x4 +x5 b.x1 +2x2 +3x3 +4x4 +5x5
Find an equation for the line that is tangent to the curve y = 3x3 - 3x at the point (-1,0). The equation is y=1 (Type an expression using x as the variable.)
y = V14x2 (3x3 – 2) 4x2 can be written as (4x2)1/4, hence the Product Rule #10. y = 4x2 (3x3 - 2) (Hint: Since function can be expressed as y = (4x2)1/4(3x3 - 2)
